I see the wood warping at the bearings (even hardwood), unless the bearings are very securely supported. For this reason it just makes more sense to me to go with two 1/8" plates on both sides of the wheels with cross-bracing.
If all we had to worry about was the strength of the chassis, then I would agree with you. Unfortunately other factors come into play, like build time and ease of maintenance. Our 2007 chassis was a good example of a solid 6wd base with dead axles that were supported on each side. It was very strong, but building it took forever and it took a lot of effort to replace a wheel.
